Porta dos Fundos is a Brazilian comedy collective that began publishing short satirical sketches on YouTube in 2012 and quickly became one of the country's most watched comedy channels. Its vinheta, the short ident played at the start of its videos, became closely associated with that format and with Brazilian internet humour more generally. As clips were shared, quoted and remixed across social media, the sting took on a life of its own, instantly signalling a sketch, a parody or a joke in the channel's irreverent style.
